Light flicker in common light sources can cause negative symptoms in individuals with light hypersensitivity, particularly those with autism spectrum disorder. The purpose of this project is to design, build, and test a portable handheld device that is capable of testing whether or not a light source possesses enough flicker to aggravate hypersensitive individuals. The prototype is a small handheld unit which contains at its core a microprocessor, a light sensor, and a display screen. Testing confirms the ability of the device to identify light flicker in several types of bulbs. The completed device meets design criteria and performs as intended during testing.


This report details the senior design project that my teammates and I worked on. I have included the official report we submitted as part of this report. On top of that, you will find a paragraph detailing my involvement in the project.
